Aitncauon ined January as, 1924. serial no. 689,217.

To all 'whom it may concern:

Be it known ,that li, W'ILLIAM PHrLLirs, n. citizen ot the United States, and resident of New York city, in the county of New `ifork and Stute of New York, have invented certain. new and useful Improvements in Combined Phonographic and Telephonie Apparatus, of which the following is a specification.

My present invention relates to sound reproducers and more particularly to eppe-A rotos for use alternatively us a phonograph or :is an amplifying telephone receiverf the latter epplication more especially for amuteur radio purposes.-

Thefinventionrelates toe; construction ot the general type described and claimed in -my copending application, Serial No. 674,

615, tiled November lll, 1923 and as to certein tentures thereof is an impioveinent thereover. l

lt is an objcet of the invention to provide aneppnratus of the above type which shall eliminate the need for monntingor disfl mountingthe` phonograph sound box or the telephonel receiver with4 respect tothe tone in order to change over from phonograph to radio operation and vice versa, and which. shall vet be capable of use at will, either :is wphonogreph for playing a record, or `us an amplifying telephone receiver or loud speaker operable from n, radio receivu ing-set.Y

Itis another object, to provide an apu puratus of the above type, the operation of which vvill be satisfactory ether as a. phonograph or as un amplifying telephone receiver, and Which-may, moreover, be einployed to produce novel eiects :for simultaneous reproduction ot phonograph records, synchronized, if desired, with colnplemerr tary telephonically transmitted Amessages or selections. A

The invention has "e preferred application to the substantially conventional phonogra-ph, the tone arin'only of which is modi- .ied to provide a double inlet, at one of which is connected the usual sound box having u diaphragm actuated from the usual stylus, and to the other of which is attached o telephone receiver. In the preferred embodiment, the entire weight of the tone arm .of the valve, so that the embodiments together with that ofthe sound-boxiand of communication. between the rudio receiverv4 and the Sound box, when the latter is in inoperative or non-record playing relation. In the. preferred embodiment, the support,-

arm of the sound box extends transversely A i across kthe tone arm and is provided with a. valve, which allows tree communication vtherefrom to the tone arm, when the sound box is in recordl playing position, but closes communication" to themtone erm when the sound box is elevated to inoperative or idle position. l 1

The branch tube for mounting the redio receiver is preferably at the delivery side valve when closed,A v)vill in no Way interrupt tween the radio receiver and the tone arm. Preferably the radio receiver supporting branch of the tone arm vextends at en acute angle to the length of the tone arm to clil y rect the vibrations lengthwise of the tone arm'and to avoid sharp angular dellec'tions of the sgund wave. .s

Since in my construction, the radioreceiver is permanently left on theV apparatus regardless Whether the latter 'is used for -phonographic or radio purposes, I'prefer to affix the electrical conductors leading to the receiver at intervals lengthwise of the tone arm land near the pivot end thereof', Where they will be unlikely to become caught and Where they will be effectively concealed.

Referring now to the drawings, I have shown' a phonograph cabinet 10, supporting aA phonograph record turn table 11 to be rotated by `the usual spring or electric motor (not shown) mounted on the lower surface of motor board 12. Within the cabinet is the usual auiplilier 18 to the upper end' of which is connected the tone arm 14. In the preferred embodiment, the tone arm is ivotally mounted upon a metal support spider 15 secured as by screws 16-to the motor board 1Q.. The spider 15 has a thrust bearingv 17 for a cooperating thrust bearing member 18 at the lower surface of aspider 19 in the tone arm. A pin 2O longitudinally through spider 19 and secured thereinto` has a bearin in a corresponding elongated hub 21 in t e support spider 15and lcorr-` stitutes the pivot mount, which permits the rotary movement of the tone arm across thev turn table for playing a record. The tone arm is illustratively shown of the taper form, the amplifier end of which telesc'o eS into the hub. 22 of support spider 15 with small clearance .Q3-therebetween. The tone .armhas the usual lateral inlet 24 upon which lthe usual S-shaped sound box jsupport 25 is attached by screw 26 which per- 'y mits pivotal displacement. ofthe neck25 with soundA box 27, to sustain the latter disengaged from the record or turn table when out of use. The sound box which includes the' usual annular diaphragm 28 of mica or equivalent material'elamped in place at its rim and actuated from tie stylus 29,' has a neck 30 telescoped with vrespect to the outer Aand fl'oui'nea the extreme endV of support arm In the referred embodiment.l the usual tone arm discribed, is cast. with an yintegral branch {l2-extending pbliquely forward at an acute angle to thoftng'th ol'` the tone arm of, and pief ,1'abl v. as shown. to somewhat 'beyond the end oll the main length of the .f tone arm.

The receivcr shown in lrivg-l is substantially of the usual head-set type and includes a casing ill which may be ot ruleanite withis confined'hy a cap 35 threaded at 37 preferably forms a metal to metal bot-v' toming enmufement with the shoulder 88 at the' base orf the nipple.

Preferably the nipple 88 is also adapted alternatively to mount the familiar phonograph loud speaker attachment, constituting an article of commerce intended to bc substituted for the sound box on an ordinary tone arm, in order to adapt a phonograph as a radio loud speaker. For this application, as will be seen in Fig. 5, the loud speaker attachment neck 40, which is .provided with the usual -rubber bushing 4l is simply teleseoped over the threads of nipple 38, the inner :face of bushing:r 4l snuefly en- 'gaging said threads, to form an adequate sound-tight connection.

Thus, my tone arm'V ma be used either with a head set receiver tiat has a s ecial socketthreaded exteriorly over 'nippe or with the usual loud speaker honograph attachment, with theusual rublier bushing which'is telescoped over said nipple.

I have found 1n a construction of the general type'invented by me,`ijn, whichthe tone arxncarries concurrently both aphonograph sound box and a radio-receiver, both kin coinmunieation with the-length of the tone arm and with eaclrothe1, that.in vthe event the `stylusclamping screw stof the'sound box is loose when the apparatus is used for radio purposes, the vibrations from the receiver 3l vmay cause annoying chatter at the sound box.- This Ifavoidb a simple construction, whereby when tlie vated to idleor ino' erative position, communication therewitlifrom the radio receiver is auton'iatically interrupted. For this purpose, the neck 44 of the sound box supportarm 25, extends transversely across the width ofthe tone arm, and has not only a'bearing inl tone arm branch 24, but an auxiliary bearing: 42 in the opposite sido of the tone arm. The neck 4l is held in place within its bearings, as shown, by the stud ot screw 26, which is threaded into branch 24- and extendsinto a peripheral groove 43 about nek 44. 'l-he neck 44 is cut-away as shown at: 45 to provide a passage preferably .f'egistering witli'tlie bore ot" the tone arm 'tll when the sound box is placed in record playing positionv` whilein the position best aov sound box is ele- 4 Lerneee l The branch 32 for the radio receiver com municates with the mam length 14C of the tone arm adjacent but at the cieiivery side receiver may be substituted fer the threaded ,4

l. A combined phonograph and amplify- .ing telephoml receiver coinprlsing through appropriate eyes 5l that may be screwed into the tone arm, the conductors extending thence out to the receiving set. Thus, it will be seen, that in the use of the apparatus a phonograph, the tonearm in its pivotal movement will in no way be hampered by the electrical-eonductor :30, and the end ot' the latter at the pivot end of tone arm 14, partakes ot' 'only small moven'lents rendering unnecessary great excessot length of wire between the phonograph apparatus and the radio receiving set.

lt it is desired to use my special tone armccnstruction Without radio attachment, a cap such-as shown at C in Fig.` 6 may be threaded over the nipple end. of the branch 32,. andthe, phonograph will operate as with an ordinary tone erm;

It will thus he4 seen thatthere is herein described apparatus in which the Several features of this invention are embodied, and` which 'apparatus in its-action attains the various'objectsfo the invention and is Well suited to meet the requirements of practical use. j

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could he made without departing .from

the scope thereof. it is intended that all matter containcdin the above description o`r shown in the accompanying drawing!` shall be interpreted illustrative and not in a limitingr sense.I
